TapeAlert
TapeAlert is a patented technology and standard of the American National
Standards Institute (ANSI) that defines conditions and problems that are
experienced by tape drives. The technology enables a system to read TapeAlert
flags from a tape drive through the SCSI interface. The system reads the flags from
Log Sense Page 0x2E.
TapeAlert Flags
Table 5-5 lists the TapeAlert flags that are supported by the Dell PowerVault Tape
Drive.

sure that the write-protect
switch is set so that data can
be written to the tape (see
the “Setting the Write-Protect
Switch on Tape Cartridges”
on page 3-4 section.) If Flag 4
is also set, the cartridge is
